A lawyer for relatives of people killed in the Germanwings crash in March says parent company Lufthansa has made a compensation offer.

Elmar Giemulla said in an emailed statement Tuesday that the company is offering 25,000 euros ($27,740) in compensation per passenger, plus payments of 10,000 euros each to immediate relatives. He described that as "completely inadequate."

Prosecutors believe the Airbus A320 was intentionally crashed into a French mountain by co-pilot Andreas Lubitz on March 24, killing all 150 people on board Flight 9525 from Barcelona to Duesseldorf.

Immediately after the crash, Lufthansa offered aid of up to 50,000 euros ($56,000) per passenger to their relatives, independent of any eventual compensation payments.
